作者用逆行气囊管扩张前列腺尿道治疗了55例前列腺增生致下尿路梗阻的患者,其中43为门诊患者,12例为无关疾病的住院患者。患者均为高龄、高危、不宜手术者,其中22例有保留尿管。扩张在静脉镇静剂或局麻下完成。55例中的46例成功缓解症状已达26个月,9例失败者需行TURP。方法:患者仰卧位行逆行尿道造影、识别外括约肌。尿道内注入局麻药。用可屈性内腔镜证实外括约肌,窥视下将导线插入膀胱、沿导线插入气囊管(直径20～35mm),定位于接近外括约肌的前列腺窝内。气囊扩张至52Psi,持续10～15分钟,然后放气,顺时针旋转导管的同时拔出导管。用可屈性内窥
The authors used retrograde balloon catheter expansion of the prostatic urethra in the treatment of 55 cases of prostatic hyperplasia caused by urinary tract obstruction in patients, of which 43 outpatients, 12 patients with unrelated diseases in hospitalized patients. Patients are elderly, high-risk, not surgery, of which 22 cases have retained the catheter. Dilation in the intravenous sedatives or local anesthesia to complete. Forty-six of 55 patients successfully remitted symptoms for 26 months, and nine failed patients underwent TURP. Methods: The patient underwent retrograde urethral imaging in the supine position to identify the external sphincter. Urethral injection of local anesthetic. The external sphincter was confirmed with a flexible endoscopical mirror. The wire was inserted into the bladder under a peep and inserted into the balloon tube (20-35 mm in diameter) along the guidewire and positioned within the prostate fossa near the external sphincter. The balloon was expanded to 52 Psi for 10 to 15 minutes and deflated, pulling the catheter clockwise while rotating the catheter. Use flexible endoscopy
